Ya, tetapi masalahnya bukan ditempat Anda melainkan di Authoritative DNS zone IP 78.112.in-addr.arpa di ISP (pemilik IP address class, biznet). Dari 4 authoritative DNS hanya 1 yang response, yang lain menolak. Sejak Biznet melakukan blocking public DNS memang DNS server mereka sering overload. Coba naikkan idle time out DNS lookup query di MDaemon Anda agar bisa menunggu response lebih lama dari DNS resolver. http://mdaemon.dutaint.co.id/14.5/index.html?default-domain-and-servers_timouts.htm Wait 60 seconds for MX DNS server responses Wait 60 seconds for A-Record DNS server responses $ host -t ns 149.78.112.in-addr.arpa 149.78.112.in-addr.arpa name server ns2.biz.net.id. 149.78.112.in-addr.arpa name server ns3.biz.net.id. 149.78.112.in-addr.arpa name server ns4.biz.net.id. 149.78.112.in-addr.arpa name server ns1.biz.net.id. $ host 112.78.149.194 ns2.biz.net.id Using domain server: Name: ns2.biz.net.id Address: 202.169.33.222#53 Aliases: 194.149.78.112.in-addr.arpa has no PTR record $ host 112.78.149.194 ns3.biz.net.id Using domain server: Name: ns3.biz.net.id Address: 117.102.126.3#53 Aliases: Host 194.149.78.112.in-addr.arpa not found: 5(REFUSED) $ host 112.78.149.194 ns4.biz.net.id Using domain server: Name: ns4.biz.net.id Address: 112.78.176.22#53 Aliases: 194.149.78.112.in-addr.arpa has no PTR record $ host 112.78.149.194 ns1.biz.net.id Using domain server: Name: ns1.biz.net.id Address: 202.169.33.220#53 Aliases: 194.149.78.112.in-addr.arpa domain name pointer mail.galva.co.id. -- syafril ------- Syafril Hermansyah MDaemon-L Moderators, running MDaemon 14.5.3-64 Beta A, SP 4.5-64 Harap tidak cc: atau kirim ke private mail untuk masalah MDaemon.
